There are currently some pic32 MIPS drivers that are in tree, and are only configured to be compiled on the pic32 platform. There's a risk of breaking some of these drivers when migrating drivers away from legacy APIs. It happened to me with a pic32 clk driver. Let's go ahead and copy the MIPS pic32.h header to include/linux/platform_data/, and make a minor update to allow compiling this on other architectures. This will make it easier, and cleaner to enable COMPILE_TEST for some of these pic32 drivers. The asm variant of the header file will be dropped once all drivers have been updated.
